Sonic 3 A.I.R

Sonic 3: Angel Island Revisited (Sonic 3 A.I.R.) is a fangame by Eukaryot which aims to be an enhanced port of Sonic the Hedgehog 3 & Knuckles for Windows PCs. The fangame, built on the Steam version of Sonic 3 & Knuckles, includes features such as 16:9 widescreen support, constant 60 fps gameplay, a new time attack mode, as well as various bug fixes and minor gameplay tweaks. The fangame requires that the player owns Sonic 3 & Knuckles on Steam (or has access to a Sonic 3 and Knuckles ROM) in order to run, although buying the Steam package is not required. The newest release comes bundled with the Oxygen Engine, which allows the user to debug their modified scripts.
